GRCS, Good Rigging Control System

TreeCo · 29th January 2007, 10:35 PM

I've had one for a few years and bought my first Hobbs Lowering Device from Don Blair back in 1990.

Yeah i wouldnt mind a GCRS,have a willow tree tommorow thats got a limb horizontal over a building could come in useful on them sorts of jobs.

Have used a Hobbs in a speedline situation, excellent tool.

Great for;

- Smooth controlled lowering
- Tightening the lowering system to reduce dynamic loading
- Cranking branches up while tip tying
- Tightening the main line while speedlining

Thats all i can think of off the top of my head.

I called into to see Don one day at his house in Big Pool, Maryland, a few years back. Unfortunately he was not there, seemingly out on the west coast doin some important sh*t. But there was a woman who was shuttin up the office/shop for the day. And i pretty much begged her to let me in to see all the gear in the basement and maybe buy some stuff.

It was like descending into Aladdin's cave!

Ropes a plenty, harnesses a go go, hardware, software, rigging, biners, spikes, you name it I saw it with my big eyes. Due to my meagre cash flow, I ended up just buying a pair of Bashlin spikes and Shigo's A New Tree Biology with the stupid little dictionary that came with it. It turned out to be a hellishly unreadable book! I always regretted not buying Don's Arborist Equipment, which is a great book even now with all it's little anecdotes about the Euc man and The Oak man. In case any of you are wondering, I am a Oak man with Euc tendencies. Pretty much like you guys I would suspect.

Still, shame Don wasn't around to talk to. Any of you guys met him?

I've met Don a dozen or two times, the first time being in 1988.

Iorek · 30th January 2007, 08:45 AM

Well is that all you have to say about him? that you met him in 88!!?
A dozen or so times!
Not very interesting is it?
Maybe not much was said?
C'mon Dan, gives some more info, Yes?

He's an interesting fellow and I think a lot of him.

Nice looking set up Ekka how do you decide on SWL for lifts? Within the limits of the rigging line I'm quessing.

Yeah that's a tough one, common sense would be appropriate.

What's the GRCS good for on lifts, be same wouldn't it, same sort of winch. I suppose never winched up more than 500kg. It's Blackies not mine, but nice to use, when tops come out you can pull in the slack ... very smooth and no shock load.

Check out the first two brakes, any thoughts? Price is nice. I have never used a GRCS or a Hobbs, do you think this would be a good way to get into something like those?

P.S. Good job on the site Ekka.

That looks great Ekka. How much did it cost to make? and did you make it?

We have a Hobbs but the GRCS would be excellent. A little more user friendly.

Ekka · 7th February 2007, 03:28 AM

I didn't make it it's another guys.

Not that hard to make, the expensive part is the winch, try ebay and yachting places maybe for a second hand one.

The winch will run up between $1K and $1.8K, then some channel and strap + weld.

You could get an electric one for that much Ekka, just need a long cable and a big alternater in ya truck!

Years ago Don Blair had a hydraulic powered bollard on the front of his truck. It was powered by the power steering pump and was quite interesting. I saw it at a seminar he was teaching.
